Reviewers mostly praise Gamma for speed: it helps them turn prompts, notes, and rough ideas into polished decks, memos, proposals, and teaching materials quickly, with many saying it cuts formatting work and makes collaboration and sharing easier. Several also like its API and embedding features for automation and richer workflows. The main complaints are limited customization, repetitive themes, missing features like charts or recording, text-formatting gaps, and occasional AI inaccuracies or weak visuals. A smaller but sharp group also reports serious support, refund, and account-access problems.
